SUMMARY
=======
 
In order to create camera projection plane fcurves, you must use the
Channel feature. The SaveKey, Camera, (Pplane) option does not have this
capability.
 
MORE INFORMATION
================
 
The following procedure shows you how to set up the Channel drivers for
creating fcurves:
 
1. Select the camera, then choose Channel, Connection Setup.
 
2. In the right-side list (Destination), select all the parameters you need
   (for example, cmpdst, cmpsz[xy], cmpof[xy]), and click Connect.
 
3. To edit the expression for each parameter, double-click on it (you
   should change the distance and X, Y size expressions so they are not 0).
 
4. To exit the dialog box and accept the changes, click OK.
 
5. To start Channels, choose Channel, Channel Run, Frame I/O.
 
6. At the first frame, middle-click the keyframe button, then drag the
   Timeline to the last frame, and click the keyframe button again.
 
You now have an fcurve with two keys in it.
 
7. Click the right mouse button to exit Channels.
 
8. Choose FcrvSelect, Camera, Proj. Plane, and All. The fcurves you just
   created will appear allowing you to use the regular fcurve editing tools
   on them.
 
9. To see the effects of this on the camera, you must turn on the
   projection plane mode in the Spreadsheet. To do this:
 
   - In the Spreadsheet, query for CAM chapter
   - Show CamPPActive parameter and make sure it's toggled ON.
